Context. Many studies have shown how galaxy properties (e.g. colours,
morphology, star-forming (SF) activity, active galactic nuclei
population) change not only with redshift, but also with local galaxy
density, revealing the important effect of the stellar/halo mass and the
environment in the evolution of galaxies. A detailed analysis of the
star formation activity in a representative sample of clusters will help
us to understand the physical processes that cause the observed changes.
&lt;BR /&gt; Aims: We performed a thorough analysis of the star formation
activity in the young massive…

Since the 2010 IAEA-FEC Conference, FTU has exploited improvements in
cleaning procedures and in the density control system to complete a
systematic exploration of access to high-density conditions in a wide
range of plasma currents and magnetic fields. The line-averaged
densities at the disruptive limit increased more than linearly with the
toroidal field, while no dependence on plasma current was found; in
fact, the maximum density of 4.3 × 10&lt;SUP&gt;20&lt;/SUP&gt;
m&lt;SUP&gt;-3&lt;/SUP&gt; was reached at B = 8 T even at the minimum current
of 0.5 MA, corresponding to twice the…

We present time-series photometric and spectroscopic data for seven old
novae. They are used to derive the orbital period for the systems V365
Car (5.35 h), AR Cir (5.14 h), V972 Oph (6.75 h), HS Pup (6.41 h), V373
Sct (3.69 h), V909 Sgr (3.43 h) and CN Vel (5.29 h). Their addition
increases the number of orbital periods for novae by ~10 per cent. The
eclipsing nature of V909 Sgr is confirmed, and in three other cases
(V365 Car, Ar Cir and V373 Sct) we detect significant photometric
orbital variability with amplitudes &#62;=0.2 mag in R. The resulting
period distribution is briefly…

In this work, we report the Photodetector Array Camera and Spectrometer
(PACS) 100 μm/160 μm detections of a sample of 42 GALEX-selected
and far-infrared (FIR)-detected Lyman break galaxies (LBGs) at z ˜
1 located in the Cosmic Evolution Survey (COSMOS) field and analyse
their ultraviolet (UV) to FIR properties. The detection of these LBGs in
the FIR indicates that they have a dust content high enough so that its
emission can be directly detected. According to a spectral energy
distribution (SED) fitting with stellar population templates to their
UV-to-near-IR observed photometry,…
